Just got a used 16 t4r and am stoked. I live in a condo with a 6"6 clearance. I want to level the front. I was told to go billstein 5100s in the front. Can I leave the back stock? My friend just did 2/1 and it looks great, but he used upcountry spacers and I was told that spacers are not the way to go. Can I go 2 up front and stock in the back? I know this is probably a stupid question, but I don't know much about lifts etc. Any advice would be appreciated. Oh and I was going to throw on some 275s. Thoughts?
